American Superconductor Issues Results for 5,000-Horsepower HTS Electric Motor Prototype.Business/Technology Editors WESTBOROUGH, Mass.--(BUSINESS WIRE)--Jan. 16, 2002 Motor exceeds development goals; next prototypes focus on ship propulsion market American Superconductor American Superconductor is a technology company based in Westborough, Massachusetts specializing in the design and manufacture of superconducting wires and power converters. It is listed on Nasdaq under the symbol AMSC. Corporation (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :AMSC AMSC Army Management Staff College AMSC American Mobile Satellite Corporation AMSC American Miniature Schnauzer Club AMSC Area Maritime Security Committee AMSC Acquisition Method Suffix Code AMSC Advanced Missile Signature Center ), a leading global supplier of superconductor A material that has little resistance to the flow of electricity. Traditional superconductors operate at absolute zero (-459.67 degrees Fahrenheit or -273.15 degrees Celsius). Experiments in the 1980s raised the temperature to -321 degrees Fahrenheit. products and power electronic converters for the electric power industry, today announced it has successfully completed load testing Load testing is the process of creating demand on a system or device and measuring its response. In mechanical systems it refers to the testing of a system to certify it under the appropriate regulations (LOLER in the UK - Lifting Operations and Lifting Equipment of the world's first 5,000-horsepower (hp), high temperature superconductor (HTS HTS Heights HTS Harmonized Tariff System HTS High Throughput Screening (biomolecular assay screening) HTS High-Throughput Screening (Pharmaceutical Industry) HTS Harmonized Tariff Schedule ) prototype electric motor. The company also said it is continuing with its plan for the design, manufacture and testing of its first ship propulsion motor prototype, a much higher torque, lower speed motor than the prototype 5,000-hp motor. The 5000-hp motor was engineered to validate the company's design of the HTS rotor field winding field wind·ing n. See field coil.

Published results establish the AMSC prototype as the world's most powerful HTS rotating machine. The company's patented, ultra-compact HTS electric motors are designed to reduce the size, weight and manufacturing costs of large industrial and ship propulsion motors, compared with conventional motors, while increasing net electrical efficiency The efficiency of an entity (a device, component, or system) in electronics and electrical engineering is defined as useful power output divided by the total electrical power consumed (a fractional expression). Industry analysts forecast the conversion to electric ship propulsion will accelerate the growth of the current $400 million ship propulsion motors and generators market to $2-4 billion annually in the next ten years. The expected compound annual growth rate for electric motors and generators for ship propulsion applications is expected to be more than 20 percent. Today nearly 100 percent of all cruise ships This is a list of cruise ships, both those in service and those that have since ceased to operate. Both cruise ships and cruiseferries are included in this list. (Ocean liners are not included on this list, see List of ocean liners. and many cargo ships have transitioned to electric motor propulsion systems. In 2000, the U.S. Navy also announced its intention to transition to electric propulsion Electric propulsion is a form of spacecraft propulsion used in outer space. This type of rocket engines utilize electric energy to obtain thrust, unlike the "normal" rocket engines that use chemical energy. motors for future Navy ships. "Motors of this type will revolutionize markets, such as marine propulsion Marine propulsion is the act of moving an object through the water or across its surface. The most common types are underwater propeller, water jet, paddle wheel and, experimentally, magnetohydrodynamic drive. and power generation, through the introduction of highly compact and efficient HTS machines and systems," said Greg Yurek, chief executive officer of American Superconductor. "We believe we're on track with our earlier forecast of having commercial HTS ship propulsion motors available for sale in the 2004 timeframe." The company's 5,000-hp HTS motor utilizes an off-the-shelf cryogenic cooling system cooling system: see air conditioning; internal-combustion engine; refrigeration. cooling system Apparatus used to keep the temperature of a structure or device from exceeding limits imposed by needs of safety and efficiency. , and its total volume, including all auxiliary equipment, is 264 cubic feet. Because HTS motors employ very high power density HTS wires, new motor designs can be used to create high power electric motors that are as little as one-fifth the size of conventional motors that use copper wires. Technical results for the prototype 5,000-hp HTS motor appear on American Superconductor's website (http://www.amsuper.com/5000hpparameters.htm), including the motor's physical characteristics and measures of its electrical efficiency. Among the results published today: - Motor Testing: Successfully passed full load testing at rated voltage, rated current and rated power. System was peak load tested to 7,000 hp at rated speed. - HTS Rotor Coils: Met or exceeded all performance goals for electrical and mechanical performance levels. - Refrigeration System: Maintained stable field winding temperature over a wide range of steady state and variable operating conditions in accordance with design goals. Net operating efficiency at full load, including the efficiency of the cooling system, was 97.2 percent. - Stator: Identified design and manufacturing changes capable of improving overall efficiency of the machine to 97.7 percent. The prototype motor is undergoing extensive post-test evaluation of all critical components. American Superconductor expects to use these evaluations and results in the design and manufacture of its HTS ship propulsion motors.
